Definitions
- This invention relates to a device for locating and locking in two specific positions a movable element sliding in a fixed frame element and influenced along the direction of sliding by resilient means.
- the invention is applicable to all push-button controlled switching arrangements in which the transition from one to the other of two specific positions of the movable element is obtained by a pressure exerted on the said element, always in the same direction and against the action of resilient means.
- Such switching arrangements are employed for instance in keyor button-operated electric switchgears, and the invention relates also to switchgears of this kind incorporating such a locking device.
- the movable sliding element is associated with a guiding element of closed profile, for example notched or heart cam shaped, which is arranged to receive a retaining finger carried on the fixed frame or casing.
- the guiding element comprises at least two, V-shaped parts, the points whereof are identically directed and substantially parallel to the direction of sliding, the pointed elements respectively controlling, when engaged by the retaining finger, the two specific positions of the movable element.
- the retaining finger is resiliently 7 attached on the fixed frame in such manner as to be able to move parallel to its axis when its end is engaged in the guiding element.
- Means are provided for causing this motion to be performed always in the same direction, this result being obtained by a particular design of the heart cam, or by varying the depth of the cam notch to form bevels and stops preventing the return of the finger backwards.
- the retaining finger In such devices, the retaining finger must be fitted on an arm movable with reference to the frame, usually pivoting with respect to'the latter, and always remaining parallel to its own axis.
- the present invention provides a device for the purpose aforesaid, in which the retaining finger is not constrained to remain parallel to its own axis but can on the contrary swing freely when its end engages the guiding element.
- Such a device appreciably simplifies the manufacture and assembly of lockable push-buttons, in particular by the elimination of a supporting arm as aforesaid, the finger being held in position merely by a spring, which makes economical mass production possible.
- the present invention is a device for the purpose aforesaid, wherein one of the elements incorporates a guide track of the heart cam type, the bottom whereof has bevels and stops, and wherein the other element incorporates retaining means, a part whereof co-acts with the guide track, the retaining means incorporating a cylindrical pin, whereof one end engages in the guide track, a resilient plate or blade attached to the other element and bearing on the other end of the said pin, and an aperture for the passage and pivoting of the pin at least in a plane substantially perpendicular to the direction of sliding.
- the guiding notch or heart cam is preferably cut out of the sliding element, for instance in the selector gear of an electric switch, the hole in which the pin pivots being made in the fixed frameand the fiat surface resil iently bearing on the second end of the said pin consisting of a leaf spring fitted on the fixed frame.
- a cam of slightly asymmetrical plan form is to be preferred as enabling the stroke of the sliding element to be shortened and thus reducing the longitudinal extension of the switch arrangement.
- FIG. 1 is a perspective view partly in section, of a device in accordance with the invention applied to a button-operated electric switching arrangement;
- FIG. 2 is a plan view of the selector element of the switch arrangement according to FIG. 1;
- FIG. 3 is a sectional view of the switch arrangement along the line III-III of FIG. 2;
- FIG. 4 is a cross-sectional view along the line IV- of FIG. 3.
- the electric switching arrangement comprises a selector element 2 carrying movable contacts and sliding in a fixed frame carrying fixed contacts connected with current taps 6.
- a spring 8 surrounding the end of the'selector element bears against the fixed frame and a button 10 and urges the selector element continuously to move out of the fixed frame.
- the selector element 2 incorporates a hollow cam notch 12 with a closed contour, either symmetrical or asymmetrical, having two points or peaks 14 and 16 (FIG. 2) and the depth whereof is variable to form several bevels and stops 18, 18 and 18", which cause a retaining finger to move along the guiding profile always in the sense of the arrow 20.
- the retaining finger is formed by a simple pin 22 (FIGS, 3 and 4) which is elastically held against the bottom of the cam notch by a leaf spring 24 attached to the frame 2, the spring 24 exerting on the pin 22 a force directed as indicated by arrow 26 in FIG. 3.
- the leaf spring 24 has at least one partially plane surface substantially perpendicular to the direction 26, along which the upper end of the pin 22 can slide freely.
- the pivoting of the pin in the fixed frame is obtained by passing the pin 22 through a hole 28 in the frame.
- the shape and size of this hole are such that the pin 22 can oscillate freely in a plane substantially perpendicular to the direction of sliding when its lower end is travelling along the cam profile 12.
- FIG. 4 shows the inclined position assumed by this pin when its end is for instance in the position 30 shown in FIG. 2.
- the pin 22 is only free to oscillate restrictedly in the hole 28 and in that direction the diameter of the hole 28 is only slightly greater than the thickness of the pin.
- the hole 24 may be of substantially rectangular form and preferably has bevelled edges 32.
- the bottom of the cam notch is sloped along the entire upper arm as above, and ends in a bevel 18 which prevents the pin from returning backwards when the button 10 is again pressed.
- the pin does not require any pivoting supporting arm so that the number of components required is reduced and the bulk of the arrangement is less.
- the leaf spring 24 is simply held in place on the frame by the pressure of the spring 8 without any connecting screw or rivet, and is prevented from becoming loose by a reverse nose 40 which engages between the frame and the selector element.
- the central core 36 of the heart-shaped cam is preferably made conical (FIG. 4) which enables pro-per guiding of the pin, while in previous cams, the sides thereof for-med cylindrical surfaces, which would prevent the free oscillation of the pin in an arrangement according to the present invention, or would at least require a considerable play between the pin and the guiding track.
- cam has been shown of heart shape, but it is obvious that many other cam shapes may be suitable, symmetrical or preferably asymmetrical, which enables a shorter stroke of the selector element, either with or without rectilinearsections.
- the cam profile may be moulded, as may be the selector element, from a synthetic plastic material.
- a device for the purpose aforesaid wherein one of the elements incorporates a guide track of the heart cam type, the bottom whereof has bevels and stops, and wherein the other element incorporates retaining means, a part whereof coacts with the guide track, the retaining means incorporating a cylindrical pin, whereof one end engages in the guide track, a resilient plate or blade attached to the other element and bearing on the other end of the said pin, and an aperture for the passage and pivoting of the pin at least in a plane substantially perpendicular to the direction of sliding.
- a device for securing an operating member in alternating successively different rest positions following successive operations thereof in the same direction comprising (a) a fixed frame element having an aperture therein,
